From recent Collier's reports: "With three new projects bringing only 100 new units to the market in total, we now have our lowest unit supply since March 2004. Based on this quarter’s demand level of 104 units per month, we currently have enough stock in the market to last until May 2008." "As a result the Dec 07 quarter has closed with 754 units available for sale, translating to 8.9 months of supply based on current demand levels. This supply is not evenly spread however, with the north precinct left with only 2.9 months of supply and the west with only 3.2 months, meaning if current demand levels remain constant both of these precincts will be completely sold out by the end of April 2008, unless new projects are released within these areas.""Rental unit vacancy rate for Inner Brisbane sits at 1.3%, showing a considerably tighter rental market than the remainder of Brisbane which shows a rental vacancy rate of 2.2%."See, e..g., http://www.colliersresidential.com/files/research/brisunitreport_dec07.pdf
